Customer:*thinking* “Um… I’ll take about a quarter — no! I’ll take less than that. I want more than a third of a pound, but no more than one quarter pound!”

(I tried my best not to laugh at the fact that a third is actually MORE than a fourth (difference between 0.33 and 0.25 respectively). I ended up slicing her one fifth instead. No wonder there’s a math joke saying that ‘5 out of 4 people have a problem with fractions!’)
